[rules-users] Web services and Drools

Oh no … I have multiple knowledge bases configured in my apps. I just use a separate Spring bean to wrap each. :)

Although for your purposes it shouldn't be too tricky to manage a pool of knowledge bases or create a reference to one per user session. The main risk would be memory usage if you have a large knowledge base or lots of facts, as a knowledge base and session is relatively memory hungry. Depends on how many users you have I guess.
